'30 Rock' Sherri Shepherd to pursue charges over Twitter bullying

30 Rock star Sherri Shepherd has met with New York City police in an attempt to file charges against Twitter bullies.

The actress took to Twitter on Wednesday (June 7) to retweet a series of threatening messages, including from a poster called @DaCloneKiller who wrote: "Somebody should drag [Shepherd] in a back alley and rape [her]."

Shepherd responded by insisting that she would not let such direct threats go unpunished.

"I am going 2 file a police report 4U threatening me. And so help me God, when I find out where U live, charges will follow," she wrote.

The former Dancing with the Stars contestant continued: "This type of bullying is one of the reasons children are killing themselves b/c there's no consequences for the bully(s)."

Shepherd later spoke with police, who apparently told her that it is difficult to pursue charges for online postings.

She explained: "The police said @Twitter has to be subpoenaed for release of @DaCloneKiller's information. I will be pursuing this.
